摘　　要：采用N902萃取剂从氨-氯化铵体系浸出液中萃取分离二价铜,考察了萃取剂浓度、萃取相比和振荡时间对铜萃取率的影响。结果表明:在单级萃取中,铜萃取率平均为98.60%;在两级萃取中,铜萃取率大于99.99%,而且铜离子也得到了富集。Using N902 reagent as extractant for separating Cu （ Ⅱ ） from ammonia-ammonium chloride leach liquor was researched in this testwork. The effects of extractant concentration, phase ratio of aqueous to solvent and vibrating time on extraction rate of copper were examined. The results obtained indicated that the average extraction rate of Cu（ Ⅱ ） is 98.60% in one-stage extraction,and the extraction rate of Cu（ Ⅱ ） is over 99.99% in two-stage extraction. Furthermore, the concentration of Cu （ Ⅱ） is also enriched in loaded organic phase.
